succesfully created this however changed the fuel to butane or acetone, used electronic cigarette lighter for ignition and used the refiller at the bottom to allow it to be fueled without dismantling it.

Works really well. Used nail polish remover which is basically made up of acetone. Huge bang and shoot as far as 30 meters. Also used old electric lighter igniter. Could improve on that part as it is really difficult to push that small button.
